Relationships Between Personal Values and Leadership Behaviors in Basketball Coaches.
2018
Background: Based on the refined theory of basic individual values and transformational leadership theory, this study focuses on the associations between coaches' value priorities and their transformational leadership behaviors, exploring the potential mediation versus moderation effect of two alternative variables in this relationship: perceived club pressure or an autonomy supportive environment. Methods: Participants were 266 basketball coaches (85.7% men) from 17 to 66 years old (M = 32.82, SD = 9.2) from 119 different Spanish clubs. On average, they had worked for their current sport clubs for 5.02 years, and they had a mean of 11.10 years of experience. The coaches were all Spanish sp…
Managers as Moral Leaders : Moral Identity Processes in the Context of Work
2020
AbstractThis qualitative study explores how business leaders narrate their personal ways of recognizing, reasoning, and resolving moral conflicts and what these stories reveal about their moral identity processes within organizational contexts. Based on interviews with 25 business leaders, 4 moral identity statuses were identified: achievement (commitment to a personally meaningful moral value framework that had been established through a period of self-exploration), moratorium (self-exploration of one’s moral value framework that was ongoing), foreclosure (commitment to a given moral value framework that was present with little or no personal self-exploration), and diffusion (neither clear…
Just a leader? Leadership work challenges and identity contradiction experienced by Finnish physician leaders.
2021
PurposeThis study seeks to improve the understanding of physician leaders' leadership work challenges.Design/methodology/approachThe subjects of the empirical study were physician leaders (n = 23) in the largest central hospital in Finland.FindingsA total of five largely identity-related, partially paradoxical dilemmas appeared regarding why working as “just a leader” is challenging for physician leaders. First, the dilemma of identity ambiguity between being a physician and a leader. Second, the dilemma of balancing the expected commitment to clinical patient work by various stakeholders and that of physician leadership work. Third, the dilemma of being able to compensate for leadership sk…
Leaders’ Gender, Perceived Abusive Supervision and Health
2018
Purpose: We investigated the role of gender in abusive leadership practices, along with the effects of abusive leadership on employee health. We tested two hypotheses regarding the relationship between abusive leadership practices and subordinates’ health outcomes. Design: At two points of measurement, 663 participants in Germany rated their 158 direct team leaders on abusive supervision and stated their own levels of emotional exhaustion and somatic stress. To test our hypotheses, we used a mixed model approach. Findings: The results show no gender differences between the ratings for female and male leaders regarding abusive supervision but do confirm that the leaders’ gender did play a ro…
Lead Poisoning in France around 1840: Managing Proofs and Uncertainties in Laboratories, Courtrooms, and Workplaces.
2021
This article reviews one of the most famous cases of lead poisoning in France, the Ponchon affair, which occurred in 1843 during a crucial period for French toxicology. The trial attracted public attention and inflamed controversy among medical and legal experts. The debate involved toxicological methods and their reliability, and gave rise to more general questions about the value of expert evidence, the way it was presented in court, and its relationship to other forms of legal evidence. I begin with a general overview of lead poisoning and toxicological research on lead compounds around 1840. I then discuss different toxicological proofs employed for detecting or preventing lead poisonin…
Distributed Leader Election and Computation of Local Identifiers for Programmable Matter
2019
International audience; The context of this paper is programmable matter, which consists of a set of computational elements, called particles, in an infinite graph. The considered infinite graphs are the square, triangular and king grids. Each particle occupies one vertex, can communicate with the adjacent particles, has the same clockwise direction and knows the local positions of neighborhood particles. Under these assumptions, we describe a new leader election algorithm affecting a variable to the particles, called the k-local identifier, in such a way that particles at close distance have each a different k-local identifier. For all the presented algorithms, the particles only need a O(…
Lead concentrations in feathers and blood of common blackbirds (Turdus merula) and in earthworms inhabiting unpolluted and moderately polluted urban …
2006
9 pages; International audience; Despite the dramatic decrease of atmospheric lead (Pb) concentrations in urban areas of most industrialised countries, we hypothesised that urban common blackbirds (Turdus merula) may still be contaminated by Pb concentrations of toxicological concern due to transfer from soil through the food chain. We sampled blackbirds and earthworms, one of their main preys, in Besan?, a middle-size city of Eastern France (where atmospheric Pb concentrations decreased from 0.5 microg/m(3) in 1987 to nearly 0 in 2002) and in a rural reference site. Lead concentrations were determined in the tissues of the different functional groups of earthworms (anecic, epigeous and end…
Local Decisions Under Central Watch: A Nordic Quality Assurance System
2013
Quality assurance or accountability, as we use the term, refers to when an actor, in virtue of contractual obligations, has the right to hold another actor responsible to a set of standards, to judge whether the standards have been met and to impose sanctions if the standards are deemed unfulfilled. In this chapter, we compare how (and if) these rights have been distributed and enacted in educational administration in Denmark, Finland, Norway and Sweden. By specifying contractual obligations, we wish to separate accountability from other kinds of asymmetric power relations, such as those between parent and child, and focus on acts of delegation and control.
Beyond the post-war Schumpeterian consensus: Governance, legitimacy and post-democracy
2010
Two distinct visions of democratic politics, both of which are in sharp contrast to Schumpeter's competitive leadership model, are to be found at the heart of governance theory. The first advocates anti-democratic solutions, aiming to depoliticize public policy, while the second supports ultra-democratic reforms promoting the involvement of citizens in policy-making. The article pursues three main aims. First, it proposes a reading of the weaknesses attributed to Schumpeter's competitive leadership model. Second, it clarifies the nature of the innovations advocated by the anti-democratic camp in its attempt to build a regulatory state, and by the ultra-democratic camp in its struggle to eng…
Non-surgical periodontal treatment with a new ultrasonic device (Vectortm-ultrasonic system) or hand instruments. A prospective, controlled clinical …
2004
Objectives: The aim of this prospective, randomized, controlled clinical study was to compare the effectiveness of a newly developed ultrasonic device to that of scaling and root planing for non-surgical periodontal treatment. Material and Methods: Thirty-eight patients with moderate to advanced chronic periodontal disease were treated according to an “one-stage procedure” with either a newly developed ultrasonic device (VUS) (Vector™-ultrasonic system) or scaling and root planing (SRP) using hand instruments. Clinical assessments by plaque index (PlI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), gingival recession (GR), and clinical attachment level (CAL) were made …
